Abstain 4 days before
Baking soda douche right before dtd
DTD once on O day, the next morning and that night.. ?

Help? :)

Well, I'm not a fan of the baking soda douche. If you must use it, I strongly recommend that you do it more like 2-4 hours before to allow your body a little time to make more EWCM to compensate for the douche.

We have seen such good results with more than one attempt. Waiting to start 3 attempts until O day actually means that most of those attempts will not capacitate in time and you will basically be limiting yourself to one attempt. I strongly suggest you start those three attempts the day before, on O-1. Have one that night, again the next morning (O Day) and then again the following night (O Day night). This is a much better way of being sure you're in with more than one attempt.
